Clearly, ext3 has moved beyond "packed permission bits" if that ever
was a production concept.

Under packed permissions, granting for OTHERS would grant for USER and
GROUP too.
Here's my question: When did packed permissions stop being used, if
they ever were?
Does anyone else remember "chmod o+w foo" silently implying "chmod
ugo+w foo" and if so how log ago was that?
